Harbour Energy plc is a leading independent oil and gas exploration and production company. The company's business model focuses on acquiring, exploring, developing, and operating oil and gas properties globally. Harbour Energy generates revenue primarily from the sale of crude oil and natural gas, with production roughly evenly split between liquids and gas. Geographically, Harbour Energy has a dominant position in the UK North Sea, which historically accounted for the vast majority of its production and reserves. Following the transformational $11.2 billion acquisition of Wintershall Dea's upstream portfolio in 2024, the company significantly diversified its geographic footprint, adding material operations in Norway, Germany, Argentina, Mexico, and North Africa. In 2025, Harbour Energy further expanded by entering the US Gulf of Mexico through the acquisition of LLOG Exploration Company. The company is also actively involved in energy transition initiatives, including the development of the Viking and Acorn carbon capture and storage (CCS) projects in the UK. Harbour Energy's competitive position is underpinned by its scale, low operating costs, and geographically diverse asset base, which provides resilience and significant free cash flow generation.
